TEXTILE FABRIC AND ITS PROCESS OF FABRICATION Filed May 2'7, 1952 United States Patent TEXTILE FABRIC AND ITS PROCESS OF FABRICATION Maurice Decloux, Verviers, Belgium Application May '27, 1952, Serial No. 290,134

Claims priority, application Belgium January 15, 1952 2 Claims. (Cl. 262) This invention relates to a new textile fabric which, after its finishing, acquires an aspect distinguishing it from known cloths, and to its process of fabrication.

In conformity with the invention it is the distinctive feature of the new cloth that it presents on one of its sides small grooves or drills having the aspect of undulations, the nap of the cloth being collected from the bottom and pushed upwards towards the crests of the grooves.

In order to give a clearer notion of this invention the drawing annexed to this specification shows, by way of example, one piece of cloth corresponding to the invention, looking at its face.

There are distinguishable more or less regular or parallel grooves A, the nap of the cloth being pushed upwards from the bottom towards the crests B of the grooves.

In accordance with the process of the present invention, the nap upon the surface of the cloth will be seized by a mechanism scraping it into tufts, between which very deep grooves, more or less stripped of their nap are located. The undulation is secured by the disposition of the scraping mechanism itself. It is in the obtaining of these grooves or drills, and of these bands of nap obtained by the operation of scraping that the fundamental novelty of the present invention lies. This process gives the cloth a perfectly new aspect. It follows from this new way of treatment of the nap that the mechanical contrivances which perform this scraping may be varied and accomplish the same result.

The piece of cloth shown in the drawing presents thus in its entirety parallelly disposed grooves or drills following the general direction of the weft. These grooves however may present an obliquity infinitely varied in regard to the weft.

Similarly the grooves can be lengthened, as in the case 2,758,354 Patented Aug. 14, 1956 of the cloth shown, without interruption, for instance on a length of 10 centimeters and sometimes even more, but they could also be interrupted after 4 or 5 centimeters and start again some millimeters above or some millimeters immediately below the interruption as long as the texture of the cloth offers, after fulling or milling, a sufiicient support as well as a certain stiffness.

In order to obtain undulatory effects not to be produced following the pattern chosen previously, except exclusively on certain portions of the cloth, the placing of templates made out of a very thin and supple metal or of any other very thin, supple and resistant material is highly commendable.

Consequently, one has only to leave empty spaces in the above mentioned templates at the spots where the formation of undulations is desired.

So as to fix the undulations obtained in such a way that they become undeformable in use, the invention provides also for the treatment of the cloth by synthetic resins with polymerisation by the use of warming cylinders applied just at the moment when the cloth winds up on its receiving roller. The definitive polymerisation is achieved during the ulterior treatment of the cloth.

From the above description, it will be seen that the cloth to be treated is subjected to a scraping mechanism in which the nap of the cloth is gathered from the bottom of the fabric and pushed upwards into crests to form undulations. These undulations may be parallel with the weft or in an oblique direction with regard to the Weft.

What I claim is:

1. The method of finishing napped cloth to obtain relief effects, comprising subjecting the nap of the cloth to a scraping device which gathers the nap and pushes it upwards into crests to form undulations in the face of the cloth.

2. Cloth provided with undulations obtained by scraping the surface in accordance with the method of claim 1.
